Chapter 45, Problem 7RQ
Summary Introduction

To define:

The term endosperm.

Introduction:

In angiosperms, the reproduction process is carried by the flower. The flower contains male and female gametophyte which produce male and female gamete. The fusion of male and female gamete results in the production of seed.

Summary Introduction

To determine:

Endosperm derived from which cell of the female gametophyte.

Introduction:

Endosperm is developed from the triploid nucleus of a flowering plant. It acts as a food storage part of the seed which provides nutrients to the developing embryo.

Summary Introduction

To compare:

The storage site of endosperm in monocot and dicot seeds.

Introduction:

Endosperm is produced by the fusion of sperm cell which contains one nucleus with the large central cell which contains two nuclei. The fusion of single nucleus sperm cell with large central cell results in the development of endosperm.
